(Urgent help needed) how to read txt file and store the data into 2D-array?

Hi, I have a GUI which allow to choose file from the file chooser, and when "Read file" button is pressed, I want to show the array data into the textarea.
The sample data is like this followed:
-0.0007     -0.0061     0.0006
-0.0002     0.0203     0.0066
0     0.2317     0.008
0.0017     0.5957     0.0008
0.0024     1.071     0.0029
0.0439     1.4873     -0.0003
I want my program to scan through and store these data into 2D array.
However for some reason, my source code issues errors, and I don't know what's wrong with it, seems to have a problem in StringTokenizer though. Can anybody help me?
Thanks in advance.

1) Next time use the CODE tags. this is way too much unreadable crap.
2) The problem is your String[][] data.... the only place I see you do anything approching initializing it is
data = new String[numLines][];I think you want to do this..
data = new String[numLines][3];anyway that's why it's blowing up on the line
data[row][col]=st.nextToken();

Want to Read the a txt file and put the data into the table colums.

I have a text file in which data is piped separated and I want to put the data in the table column.
Eg.
Text File Column
First_name|Last_name|address|phone_number
Database table:
first_name ,last_name,address,phone_number
It's very urgent.
Thanks For your help in advance.

How can i re-enable/restore a disabled iPad and keep the data without using a laptop or iCloud

Hello,
Is there a way to re-enable a disabled iPad and maintain the data taking into consideration that no iCloud backup was made and the computer it was last synced with was not available? any idea?

No, sorry. Without a backup in iCloud or iTunes, you will have to set it up as if new and anything on it will be lost now.
You can always re-download purchased apps and content (other than audiobooks) once it is restored, from the respective iTunes or App stores.

How to skip certain lines for a txt file and insert into array

so here is my question:
i had a file to read, and it requires to input into the array starting from a certain line
example:
4
john 25 M
mary 22 F
lee 20 M
faye 10 F
faye john
mary john
mary faye
i want to insert the friend list, starting 5th line into a 2d array, which is the int from first line +1.
can someone help me with it?
i believe there is a skip method and stuff..
but just dont know how to use it
may someone tell me how to do tat?

the thing is i think that takes too long and it is not efficient..
however...i just solved it with a better method
Scanner in = new Scanner (reader);
int size = Integer.parseInt(in.next());
BufferedReader insert = new BufferedReader(new FileReader(new File(input)));
String line = null;
int count = 0;
int startAtLineNo =size+1; // 0-based
while ((line = insert.readLine()) != null) {
if (count >= startAtLineNo) {
/* do stuff */
System.out.println(line);
// else ignore
count++;
thanks anyways

What I wanna do is to read all the data above and buffer them in a queue for each user( there are only 10 users in total).
I already created a class called Class packet:
public class packet {
    private int timestamp;
    private int user_id;
    private int packet_id;
    private int packet_seqno;
    private int packet_size;
    /** Creates a new instance of packet */
    public packet(int timestamp,int user_id, int packet_id,int packet_seqno, int packet_size)
        this.timestamp = timestamp;
        this.user_id=user_id;
        this.packet_id=packet_id;
        this.packet_seqno=packet_seqno;
        this.packet_size=packet_size;
}then I wanna to create another Class called Class user which I can create a queue for each user (10 users in total) to store type packet information. the queue for each user will be in the order by timestamp.
any idea and sample code will be appreciated.

Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

How can I open Microsoft doc attached to my iPad email

How can I open Microsoft doc attached to my iPad email

The document should open as an email attachment in the mail app. Did you tap on the icon in order to open the file?
However, if you want to save or edit the document, then you will need a Word compatible app on the iPad. pages, Documents To Go, quick Office Pro ... And others are available in the app store.
But you can open and read it right from the mail app as an attachment.
